about dcmgr/config/db/migrations/0001_v1110_origin.rb, please discuss how to add an new column on an existed table.
i think it is better to create other file, like 0002_add_instance_nic_id.rb, because we can upgrade to latest schema from old schema for a service which already started. we should prepare the migration path.
